Infectious mononucleosis in children and differences in biomarker levels and other features between disease caused by Epstein–Barr virus and other pathogens: a single-center retrospective study in China

Abstract

Background Infectious mononucleosis (IM) is a common viral infection that typically presents with fever, pharyngitis and cervical lymphadenopathy. Our aim was to identify the different pathogens causing IM in children admitted to our hospital and to analyze the differences in features of infection with different organisms. Methods We retrospectively analyzed the data of children aged 0–17 years admitted to Wuhan Children’s Hospital during 2013–2022 with IM. We compared symptoms, physical findings, blood counts, and serum biomarkers between patients with IM due to Epstein–Barr virus (EBV) and IM due to other pathogens. Results Among 1480 enrolled children, 1253 (84.66%) had EBV infection, 806 (54.46%) had M. pneumoniae infection, 796 (53.78%) had cytomegalovirus infection, 159 (10.74%) had parvovirus infection, 38 (2.57%) had influenza virus infection, and 25 (1.69%) had adenovirus infection. Receiver operating characteristic curves were used to determine the area under the curve for alanine transaminase (ALT), aspartate transaminase (AST), Alkaline phosphatase (ALP), total bilirubin (TBil), indirect bilirubin (IBil) levels to assess liver damage, and for creatine kinase (CK), CK-MB, and lactate dehydrogenase (LDH) levels to assess myocardial damage. The optimal cutoff values of these biomarkers were then determined. In multivariate analysis, elevated ALT, AST, ALP, TBil, and IBil were independently associated with liver damage, and age <3 years, CK, CK-MB, and LDH with myocardial damage. Conclusion Evaluation of biomarkers and pathogen detection may help physicians to take preventive actions to avoid serious complications in children with infectious mononucleosis.

“…In this case, characterized by an enlarged pancreas visualized by abdominal ultrasound, the etiological diagnosis was only achieved by a positive serology for the presence of Epstein-Barr virus VCA IgM and IgG. The review of the few cases described in the literature draws attention to the importance of differential diagnosis that include specific serological research even in the absence of the classic clinical and haematological characteristics of Epstein-Barr virus infection [113]. Generally, Epstein-Barr virus-associated acute pancreatitis is characterized by a favorable prognosis, with a spontaneous resolution [114,115].…”
